IPC: H04L12/42
Filed: 1989-11-10
Abstract: The exchange system comprises stations connected by a closed-loop having two rings (A1, A2) using a method of access by token, and functioning in load-sharing mode, each ring ensuring the totality of exchanges in case of a failure of the other. Each station comprises one adaptor (1, 2) per ring, a coupler (C) and a terminal (T). Each adaptor ensures only the procedures of the low-layer level 2 and of the level 1. The coupler comprises a processor which ensures, with the aid of a high level protocol 2 and 3, the management of the load sharing between the rings, the switching of the station onto a ring in the case of failure of the other ring, the protection against transmission errors, the desequencing and the duplication of the messages, the adaptor and ring failures, and the instantaneous halting of traffic by removal or insertion of a station.

Abstract: This is an inspection cover having an inspection frame (1) and an inspection lid (2). The inspection frame (1) has aluminium frame sections (4), and the inspection lid (2) has aluminium lid sections. The frame sections (4) are reinforced as it were by steel retaining sections reaching beneath them and by steel corner angles (6) overlapping them, and the lid sections are reinforced as it were by steel-plate strips reaching beneath them and by steel corner angles (6) overlapping them, so that, in the event of attack by fire, a steel skeleton remains for both the inspection frame (1) and the inspection lid (2) even if the aluminium sections continue to melt. The inspection cover is thereby distinguished by high fire resistance or prolonged fire resistance.

IPC: H04H20/42
Filed: 1989-11-23
Abstract: ABSTRACT      Method and apparatus are provided for transmitting, receiving, and reproducing digital audio signals as discrete carriers similar to standard FM broadcast signals.  An audio signal is digitized using, for example, adaptive delta modulation techniques.  Several channels of audio information, such as left and right stereo channels and a second audio program ( "SAP" ) channel can all be digitized and incorporated onto the digital broadcast signal carrier.  The digitized audio signal may be modulated using multiphase modulation of the carrier of an FM broadcast band signal.  A plurality of audio channels may be digitized and transmitted over the airwaves, or over a cable transmission network.  Channels of nondigitized audio channels may be interspersed with the digitized audio channels.  Source material for the digitized audio channels may be provided to a cable headend over the cable transmission network outside the FM band, and rebroadcast over the cable transmission network in the FM band. Advantageously, an "extended" FM band between 72-120 MHz is employed to provide more channels than the "standard" FM band of 88-108 MHZ.

Title: Method for the remote-controlled substitution of a defined program part of a tv program by a separately transmitted program part for defined, selected receivers, household terminal for executing the method and method for operating a household terminal
IPC: H04H20/76
Filed: 1990-01-18
Abstract: In a method for the remote controlled substitution, in particular of a defined advertising spot by a test advertising spot for selected receivers, it has been provided that bi-phase modulated start codes are transmitted in the picture lines outside of the TV picture visible on the video screen for the control of the address-distributed TV signals for the program part to be substituted.  To execute this method, a household terminal in the form of an interposed device for commercially available TV receivers has been provided, which is distinguished by at least two tuners, the outputs of which are connected with a fade-over component, as well as a decoding circuit arrangement for decoding the switching code signals and for contact with the fade-over component.  To achieve a field-exact switchover, i.e.  one undetectable by the viewer, a synchronous frame detector arrangement is additionally provided, which field-exactly switches over the fade-over component from the original program to the synchronously transmitted substitute program in the vertical black-out gap.

Title: Fluid flow reversing and regulating ring
Inventor: MAYHEW PHILLIP A
IPC: F15D1/14
Filed: 1990-03-12
Abstract: A fluid powered mechanism has a housing with a generally cylindrical shape and circumferentially adjacent axially extending primary and secondary fluid passageways.  Exhaust direction and rotary limit speed are controlled by a flow reversing and regulating ring having a first face with a thru slot and an adjacent blocking flange and a second face having a turning flange which is the reverse of the blocking flange of the first face.  The flow reversing and regulating ring is color-coded to indicate the size of the fluid flow passageway and, thus, the limit speed provided by the ring.  The rotational limit speed and the exhaust direction are determined by selection of the color-coded flow reversing and regulating ring and by its orientation in the tool.

Patent CA-2015153-A1 (CA)
Inventor: SCHIRMER HENRY G
IPC: B29C55/28
Filed: 1990-04-23
Abstract: Polymeric, thin oriented films can be made by use of a combination of a hot blown process and a blown bubble process, i.e. a double bubble process. The resulting film has use in replacing PVC for in store stretch wrap applications. Very low density polyethylene, VLDPE, is an especially preferred material for this process. It may be used as a monolayer, or as one layer of a multilayer structure.      In practicing the invention, the polymer is extruded and hot blown, and heated to a temperature above its orientation temperature. This heating can be accomplished by the use of a heated liquid reservoir or sock disposed at the lower end of the primary bubble, inside the bubble. The hot blown heated film is then passed through a first set of pinch rolls, re-inflated into a blown bubble, and collapsed at a second set of pinch rolls. Thin, tough and elastic packaging materials are obtained by this process.

Abstract: ABSTRACT VEHICLE SYSTEMS FOR USE IN   COSMETIC COMPOSITIONS Disclosed is a unique vehicle system which provides a desir-able rheology to products formulated therewith, enhanced disper-sion  of  actives  therein,  and  improved  deposition  of  actives therefrom.  This vehicle  system comprises  a primary thickening agent  which  is  a  nonionic  long-chain  alkylated  water-soluble polymer, and a secondary thickening agent which is a water-soluble surfactant,  dispersed  in  a  compatible  solvent.   Optionally,  a rheological aid, which is a chelating agent may be included in the vehicle system.  Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be  included in the vehicle system.   These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin.  The vehicle systems are particularly useful  in hair care compositions, espe-cially  rinse-off hair  conditioning  compositions,  because  they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

Abstract: An apparatus for locking a packer against premature actuation in a well bore.  The locking apparatus includes a sleeve attached to a lower end of the packer and spring biased locking members adjacent to the sleeve.  When in a locked position, lugs on the locking members engage a groove in the sleeve and prevent longitudinal movement of a mandrel in the packer with respect to the packer elements.  When the locking apparatus enters a liner in the well bore, the locking members are biased radially inwardly, disengaging the lugs from the groove, so that the packer mandrel may be actuated and the packer set.

Title: New carrier catalyst for the polymerization of ethylene
Inventor: ALA-HUIKKU SIRPA
IPC: C08F4/654
Filed: 1990-09-04
Abstract: A problem in the conventional olefin polymerization catalyst systems, the procatalysts of which are based on a solid carrier and a titanium compound and an electron donor on its surface, is that unsufficiently high activities are achieved by the morphology of the carrier. Moreover, the active age of such a catalyst in the polymerization is too short. These problems have now been solved by the olefin polymerization catalyst system according to the invention, the procatalyst of which comprises a solid carrier and a layer on its surface consisting of a titanium compound, a magnesium compound and an electron donor. The advantages of the invention become more emphasized when using monocyclopentadienyl titaniumtrichloride as the titanium compound.
